I have seen this happen every now and again and was wondering if anyone else has had this problem. I lock the car in the eveing after getting home and leave it overnight, in the morning I go to unlock the car and the remote locking doesn't work. I put the key in the drivers door, unlock and this just unlocks the drivers door, all other doors stay locked. I put the key in the ignition and when I start the car all the doors unlock. This happens maybe once a week and I have replaced the battery so I know thats good in both keys and it doesn't matter which of the keys I use. I switched to the 2nd key which was brand new and never used, put a new battery in it just incase but every now and again the same thing happens. Its no big problem just stranage. Anyone else experienced this?
